"""
Salt states to create and manage VMware vSphere datacenters (datacenters).

- pyVmomi Python Module

States
======

datacenter_configured
---------------------

Makes sure a datacenter exists and is correctly configured.

If the state is run by an ``esxdatacenter`` minion, the name of the datacenter
is retrieved from the proxy details, otherwise the datacenter has the same name
as the state.

Supported proxies: esxdatacenter


Example:

1. Make sure that a datacenter named ``target_dc`` exists on the vCenter, using a
``esxdatacenter`` proxy:

Proxy minion configuration (connects passthrough to the vCenter):

.. code-block:: yaml

    proxy:
      proxytype: esxdatacenter
      datacenter: target_dc
      vcenter: vcenter.fake.com
      mechanism: sspi
      domain: fake.com
      principal: host

State configuration:

.. code-block:: yaml

    datacenter_state:
      esxdatacenter.datacenter_configured
"""
